To (1f/. Irl/om, if 7:1.1/ concern:

Be it known that I, ALFRED HENRY Por- BURY, a citizen of the United States, and a resident of Portland, in the county'of Multno- 5' mah and State of Oregon, have made certain new and useful Improvements in Wrapping'- Machines, of which the following is a specifi cation.

My 'invention is an improvement in wrapping-machines; and it consists in certain novel `constructions and combinations of parts hereinafter described and claimed.

Referring' to the drawingsiorming a part` hereof, Figurefl 1s a ersp-ectlve v iew of my."

'c, having their ends flanged, as at c', and l improvemel'lty from t ie ont. Fig. 2.is a

similar view from the left lside;

rear perspective view.- "FigL 4 is asimilar view looking from' the right and rear'. Fig. 5

is a erspectivevi'ew looking. down up'on the 2o mac line. -Fig is a top planview with the operatinsbshaft and appertaining parts re-V moved. Fig. 47 is a sectional view through the -plunger'. and. the folding mechanism.v ,.Figs. 8 to 13, inclusive, show the, different z steps in the folding operation. Fig. 1 4 is a section; through the wrap )ing devices'on the line of the folding-box. `ig.- 15 is a detailof the cutting mechanism and the feed mechanism for the aper-feeclim'grolla F ig'. 16 is 'a 3o detail of tie paper-feed stop- 'mec'zhani-srn.l and Fig; 17 is a detail of the folding-box. 111' t e embodiment of my improvement l: herein shown and described. the .mechanism is mounted uponv a base-plate A; having a 3 5 portion thereof at the front removed, as at a,

the-said base-plate being provided uponv its under face, on each side oftheremoved portion, with rails az a3, the one rail. supported by brackets a',"securedjto the base, and th'e 4o other rail a su porteddirectly by the base* A plurality of s rafts la," a5 are journaled in the rails at opposite endstliereof, and-each shaft has secured thereto a hexagonalwlieel a a7,

whilethe rear shaft ai has also` secured 'thereto-aratchet-wheel as.'

i Apawl-arm a-is loosely mounted upon the r'rear. sbatte and is provided Witha'springlpressed paWl al. 'for engaging the .ratche-tf l wheel, the paWl-.arm being'actuated lbv a'link 15p connected to one arm.- of the rock-shaft 1l gli,

'ournaled upon a bracket a,'rising from the c'tlierrelm'` otthjerockfshsft B, and a spring d", connected to the pin el" before descrlbed, and the lower arm .of 'thef-xco' is providedwith a roller al, e aging a cam b upon `the drive-shaft B, journa ed in brack-V ets 0.15, secured to the base and driven by a pulley b', having on its inner side a hand- Wheel b, from any suitable' source of power; (Not shown.) A rod a.19 is secured tothe bracket ela and rojects forwardly -therefrom, the said rod raving passed through the free end thereofa pin al?, to one of 'the ends of Awhich is' attached a. spring al, connected 4 with the lower arm of the rock-lever d, whereby to return the pawllarm to its original position after its movement b v the cam.

A cha-in C, comprisinga pluralityof linksy .o

their sides open, is mounted upon the -sprocket-wheels a a7', the relation of the ratchet-Wheel and the hexagonal wheels be. ing such that the movement ,of the ratchetwheel thedistance-of one tooth moves the chain a distance equal to the length of one flink. A cross-banal is .securedl tov the rails et a3' at about the center of the upper run of 7 5 'the chain and is provided with lateral projec#` f tions a2, arrangedbeneathl the chain, where.- by to sp ort the upper run thereof in itsV travel an keep the same in proper 'alinement. I v S- 8o. ,A segmentaltrack D, equivalent in length to ninety degrees/of the. circle upon which:

1 it.- isdrawn, 1s secured to theu'pper faceof the Vbase near -the inner end of the upper run ofv the-chain, the said track having radial arms extending from each ,end thereof to ai vertical bearing 'for a bolt d', corresponding in .osition to the center of the circle upn 'which the track is formed. A carrier-arm d? is pivoted u on the bolt d', the said arm being provide with a lug d", corresponding in length to the Width of the track and fitting y thereinfand adjacent to the bolt d the 'arm .is'f rovided with a projection d3, connected' by e link fz with one erm of a rock-Shaft 1595" journaled upon the bracket a, thef-otheifl'" arm of the rock-shaft bein provided with a-roller d, engaging a'cam pponfthe shaft rock-shaft is .provided 'Afor maintaining'the roller in contact with the cam. A "pad d' is. mountedupomtlie bolt d. mallylies with its ace d abou across the folding-box E, to be hereinafter derolls and the folding-slot,y with suitable pascribed, being retained `in this' position by a per-guides to assure the correct passing of the spring dx, connected to a radial arm of the paper tothe paper-slot.

segmental track. j

As the caramel is moved toward the foldi ing-box by the carrier it engages the guideover the folding-box IE, when the plungerpad d8 upon its forward side and moves the said guide-pad. with it until it is directly descendin carries it down upon the paper and outo engagement with the carrier and the guide-pad. The, projections d dz on n .the carrier and the guide-pad, respectively, -are designed to engage when no "caramel is fed to .the machine andfpush the lpad back out of the wayof the descending plungerl thus avoiding injury to theI moving parts.

j It will be understood that during the vmovement of the chain'the carrier-arm (Z2 lies with the lug dg on the outer side of the chain in such position that when the chain stops the lug registers with the open end of the link, and at this point the cam b2 operates the rock-shaft to swing` the projection of the arm along the'segmental track, where- Vby to move the caramel supported by the ylink against the face of the guide-pad d5.

The carrier-arm d2 is returned to its original position before the chain again moves.

APrevious to the before-described movenient of the caramel bythe carrier-arm a strip of paper is pushed into positionin the paper-'sloteo just above the folding-box E, the paper beingfed in a continuous strip from a reel H, mounted upon brackets am,

secured to the base, the strip passing downf wardly from the reel and through a series of tension-rods h L h2, fastened in the base of the brackets a, the paperpassing under the rod h, over the rod 7L', and beneath the rod h2 to a pair of rubber feeding-rolls 7i? h4, journaled in bearings in brackets a. secured to the base. y

,The upper roll h3 of the feeding-rolls is provided with a pinion 7L", meshing with a gearwheel h upon a stud 717, projecting. from one ofthe biackots d2, T he stud L7 has fitting thereon aratchet-wheel hm, secured to the side of thegear-wheel h and engaged by a spring-pressed pawl 7L upon a pawl-arm 7i?, loosely mounted on the stud and connected by a link lil-3 to one of the arms of the rocklever h, the other arm of the rock-lever being provided with a roller 7L, contacting with a cam b upon the drive-shaft B, the

y roller being maintainedvin contact with the ets a,23 ,and a movable shear-blade K, pivoted l n a projecting stud in a bearing provided in the righthand bracket 0,23. The cutting mechanism is arranged between the feeding- -niences itsforward movement.

.rock-lever being provided with a roller 1:5,

contacting with the cam b5 upon the driveshaft B and normally maintained in contact therewith bv mechanism to be later described A A plunger e is arranged directly above the folding-box within a casing e', the casing being secured to the base in any suitable mander. The upper end of the plunger is provided with a bearing e, in which is ourna ed a roller e, engaged by a cam b3 upon the drive-shaft B, and the bearing is provided with lateral lugs e4, having downwardly-proj ecting pins e5 for engaging vertical openings in the plunger-casing, and springs e encircle the pins between the lugs and the top of the casing, whereby to maintain the roller e3 in contact with the cam.

After the caramel is moved into position over the folding-box by the carrier-arm, Fig.

8, the plunger moves downward, carrying the caramel and the paper into Ithe box,- uptui'ning the sides of the paper, as shown in Fig. 9, thus inclosing the caramel upon three sides. The carrier-arm meanwhile is returned to its original position, andv the plunger is again moved upward by the springs el. The first top-folder m is now moved forward to make the first top fold, the said folder comprising. a plate movable through a slot in the foldingbox, the outer end of the folder being connected by links m with one arm of a rock-leverv 'm2, journaled on a pin m32, connected with one of the brackets alf", the other arm of the rock-lever being provided with a roller m3, contacting with a cam b5 upon the drive- Shaft B. The arm of the rock-lever m2 provided withthe roller has projecting upwardly therefrom an arm m5, to .which is attached a spring m, connected at its other en d with an arm k, rojecting upwardly from the arm of the roc -lever c* provided with a roller ks,

the tension of the spring maintaining bothpI therollei` mi* and the roller ki in contact with the cam.

As the folder m commences its return movement the second top-folder m com- The folder m likewise consists of a late moving in.a slot through the opposite wall of the foldingbox from the folder m, the outer end of the folder being connected by links m7 with one ofthe arms of a rock-lever m, ivoted on a pin m39-, projecting from the brac et a15 and having j'ournaled in the other arm thereof a roller m2, engagingv a cam b upon the drive-shaft B, the roller being maintained in contact .with the cam b means'of a spring m2", Se-

The o posite endof the shaft is provided with-a link h1", rigidly connected therewith, and pivoted lto the 'link is a stop-bar h2", slidably mounted in acted upon by a `spring 71,22, securedto the stop-plate and to one of the .brackets h. l The lbase-plate A is'provided with an opening af for-. .receiving the-pawl-liolder ha in. its 6o. downw ard. 1not1on. It will be noticed from inspection of Fig.- '1 5 that the ratchet-wheel t1."is .fprovided with four teeth, so with each (pinety agrees.' .It will be evident @dreaded from the escription that-when each f the caramel.

links of the chainV is provided with a caramel the feeler h will be retained in an elevated should, f i

vented no feed of the paper will result on the upward motion of the pawl-holder.

In o eration, power being applied to the drive-s aft, the caramels are supplied to the links of the chain in any desired manner.'v Eachrevolution ofthe drive-shaft moves the chain one link, stopping the chain cach time in such position that one of the links is o pos site the carrier-arm and in position to ave `the j caramel removed therefrom During the movement of the chainthe stripoi" paper is being fed in to the paper-.slot beneath the plunger by therubber-covered rolls, and imimediately following the carrier-arm swings tol sweep the caramel lfrom the link and into Aposition under the plunger, the fall of the caramel (edgwise) into the folding-box being prevented bythe ide-pad, which catches the forward'side o the caramel and stops it in the proper position for engagementby the plunger. In the meantime the pa er beneath the caramaljis severed from t e. strip and the plunger moves the caramel and the paper downwardintothe folding-box, thus upturning the paper at' the sides of the cara- -mel. At this point the plunger is withdrawn and the first side-folder moves forward to lay the`upstandin side of the aper upon the Ast e first side-fo der commences its retiu'n movement the second side-folder begins its forward movement, thus laying the opposite upstanding side down upon the first: folded side. .Through the connection of the second side-folder with the end-folders the movement of the second side-folderand the end-folders is synchronous; but since the end-folders have 'a greater distance to travel they do not come into operation until .tlie second side-folder has entirely completed its `forward movement.- Before the end-folders commence their upward movement the iirst corner-folder 1s moved forward, folding down the corners upon the ends of the caramel, and

as they withdraw the second corner-folders `move forward, folding the opposite corners.

At this point, a new stri of paper having been fed forward above t 1e caramel already folded, .a new caramel is placed thereon and Ime-:plunger moves downward, forcing the wrapped caramel into achute N, forming an entension'of `the folding-box'and passing downward-through the base. The'fmovef whereby to bring the open sides of the links' ment of the Wrapped caramel into the chute makes the final iolding, turning the already folded ends up against the ends of the caramel, thus completing the wrapping opera* tion.

The sides of the folding-boxE are tormed by springlates ex, secured to the opening in the base-p ate A, through which the caramel passes to the chute N, the said plates possess ing sulicient rigidity to retain the caramel and wrapper in proper position in the folding-box.
